The Australian Prudential Regulation Authority yesterday clarified its reporting requirements for banks under the Basel II capital adequacy regime.Probably the main twist is that banks get six weeks, rather than a proposed four weeks, to file quarterly returns for those working under the "advanced" version of the regime.A second is that banks working to the advanced version of Basel II must still file the same reports as required under Basel I, probably so APRA can make sure banks do, in fact, maintain equivalent levels of capital.
